The right option is; The body cannot make them.

Amino acids are organic compounds that perform many important roles in the body including building of proteins, and production of neurotransmitters and hormones. Based on some factors, amino acids are grouped into two; essential, and nonessential amino acids. The essential amino acids are the amino acids that the body cannot produce on its own, and must be obtained by eating various foods. The nine essential amino acids are; isoleucine, histidine, leucine, phenylalanine, lysine, tryptophan, methionine, threonine, and valine.

A client has thin, dark-red vertical lines about 1 to 3 mm long in the nails. Which diseases are associated with this physiologi

qaws [65]

Answer:

- Trichinosis

- Bacterial endocarditis

Explanation:

Trichinosis is a parasitic infection that has as its etiological agent the nematode parasites of the genus Trichinella, and the species of greatest interest to human medicine is Trichinella spiralis. One of the first and characteristic symptoms of infection is the swelling of the eyelids, which appears around the 11th day after infection. Subsequently hemorrhages appear in the eye sclera and in the back of the eyes, eye pain and photosensitivity. Then there is the appearance of muscle pain, along with a rash and bleeding below the nails causing dark red vertical lines about 1 to 3 mm long. The pain is intense in the muscles linked to breathing, chewing and swallowing.

Bacterial endocarditis is always associated with a bacteremia that the immune system has failed to counteract. In other words, the presence of bacteria in the bloodstream, which is usually sterile, represents an important cause of bacterial endocarditis, an infection that affects the inner membrane lining the heart and heart valves, especially if they already have a disorder. The disease sets in when bacteria from various parts of the body - from the mouth mainly, but also from the skin, intestines, respiratory tract, and urinary tract - are carried through the bloodstream to a heart valve or other damaged endocardial area where fix it. Among the many symptoms, indicative of the presence of this disease in the body are thin dark red vertical lines about 1 to 3 mm long in the nails.

After doing PCR on the same region between two individuals, you notice that each person's DNA yielded pieces of different sizes.

vitfil [10]

Answer:

C. This is an example of VNTRs.

Explanation:

VNTRs are Variable Number Tandem Repeats. These are short sequences of DNA repeated in tandem (that is, the sequences are repeated one next to the other) a certain number of times. Unrelated individuals have a different number of repetitions for a certain region of the DNA, therefore the total length of the fragment is variable among individuals, depending on how many times the short sequence is repeated.
